@7221; aEZarheyS Patented June 7, 1932 UNITED STATES PATENT OFFICE RALPH AUGUSTUS YEOMANSON, OF LONDON, ENGLAND, ASSIGNOR TO BRITISH- AMERICAN TOBACCO COMPANY LIMITED, OF WESTMINSTER, ENGLAND SEALED CAN OR REGEPTAGLE Application filed July 18, 1930, Serial No. 468,952, and in Great Britain July 2-6, 1929.

This invention relates to cans or receptacles of which the tops are sealed by tagger tin protected by a cap rotatable on the top of the can or receptacle. Such cans as used heretofore are provided with a seal-breaking device consisting of a cutter radially adjustable in slots provided in the cap so that after the cutter has been adjusted to cutting position in the cap and the cap forced on the can, it will perforate the tagger tin, and then by rotating the cap on the can a circular out can be made in the said tagger tin sufficient to enable it to be removed. In such devices it is not possible to hermetically seal the can by replacing the cap as the latter has perforations to carry the cutter and must fit loose enough to rotate on the said can.

This invention has for its object to provide an improved can, or receptacle, of the aforesaid kind and consists in providing the receptacle, with an outer cover which screws onto, or is otherwise removably connected to the receptacle, so that after the tagger tin has been removed, as aforesaid and the cutter carrying ca has been operated to effect the unsealing of the receptacle, the said cap together with the cutter thereon, can be removed and dispensed with and the said receptacle, be closed, when desired, by replacing the said removable outer cover. A washer, of rubber or other suitable material, may be interposed, if desired, between the outer cover and the rim of the receptacle, to ensure a hermetical closure.

A manner of carrying out the invention is illustrated in the accompanying drawing wherein Figure 1 is a sectional view of the complete can before the tagger tin seal is broken, Figure 2 a similar view of the can sealed after the said tagger tin seal has been broken, and Figures 3 and 4 an inverted plan 7 and an elevation, respectively, of the removed cap and cutter.

In this drawing the seal breaking device consists of a cap 2 arranged to fit a reduced neck 3a formed on the can or receptacle 3, and is provided with a cutter 2a of the known kind adapted to operate over and cut through a tagger tin seal 3?) in the usual manner when the cap 2 is rotated on the can 3. After the unsealing operation, the cap 2 with the cutter 2a thereon is thrown away, the can may be re-sealed as often as required by an outer cover 4 screwed on threads 30 provided on the can 3 below the reduced neck 3a. The outer cover 4 is provided with a rubber washer 5 which bears on the rim of the can 3 and ensures a hermetical closure.

Instead of carrying the cutter 2a on a complete cap 2 it may be carried on any suitable ring or like device adapted to fit on the reduced neck 3a.

The outer cap 4 instead of being arranged to screw on the can 3 as shown, may be connected thereto by any other suitable fastening device such as a bayonet joint.

I claim:

A receptacle having a reduced, neck, a tagger tin hermetically sealing said receptacle, a seal breaking device comprising a cap protecting said tagger tin and fitting over said reduced neck, a cutter on said cap for removing said tagger tin, in combination with an outer cover having screw threaded engagement with said receptacle below said reduced neck, whereby after removal of said cover and operation of said seal breaking device to unseal the receptacle the seal breaking device may be discarded and the receptacle closed by replacing said cover.

In testimony whereof I have signed my name to this specification.

RALPH AUGUSTUS YEOMANSON.
